My first guess would be that you have a bad potentiometer or a gear missing some teeth in the left flap servo.

In case your haven't seen it, there is a lot of information about setting up a sailplane with the 8U or 9C in the thread:

A standard set up disables knob 6 and uses OFFSET in setting up the flaps.

i'd like to move flaps to switch g 3 position,but cant understand this futaba manual for 8u

What kind of model are you attempting to program? .60 size jug sounds like a power model but this is the Thermal forum so I'm not sure what to think. Putting flaps on switch G should be simple but what do want the flaps to do and what else do you want the program to do? This is largely dependent on the type of model you are programming, I guess.

sorry I need to be in the power forum

It does sound like you have a mechanical issue with the servo. I would suspect you have a busted gearset. Everytime I've had a servo that did not move smoothly, it turned out to have a damaged gear.

Good luck.
